摘要: Three ruthenium(II) polypyridyl complexes, [Ru(phen)2(mip)](ClO4)2 (1) (phen =1,10-Phenanthroline), [Ru(bpy)2(mip)](ClO4)2 (2) (bpy = 2,2’bipyridyl) and [Ru(dmb)2(mip)](ClO4)2 (3) (dmb = 4, 4′-dimethyl 2, 2′-bipyridine), were synthesized with an intercalative ligand mip (2-morpholino-1H-imidazo[4,5-f][1, 10]phenanthroline) characterized by 1H, 13C–NMR, IR, UV-vis, mass spectra elemental analysis. pH effect, ion selectivity (cations, anions) solvent sensitivity of complexes studied. The interaction these DNA was performed using absorption, emission spectroscopy viscosity measurements. experimental results indicated that the two interacted calf thymus (CT-DNA) mode. BSA (Bovine Serum Albumin) protein binding studied UV-visible fluorescence techniques. capacity explained theoretically molecular docking method.
